This brief focus on drilling of polymer matrix composites for aerospace and defence applications. It gives an introduction to machining of polymer composites and discusses drilling as a processing of composites.
Machining is one of the most important manufacturing processes. Parts manufactured by other processes often require further operations before the product is ready for application. “Machining: Fundamentals and Recent Advances” is divided into two parts. Part I explains the fundamentals of machining, with special emphasis on three important aspects: mechanics of machining, tools, and work-piece integrity. Part II is dedicated to recent advances in machining, including: machining of hard materials, machining of metal matrix composites, drilling polymeric matrix composites, ecological machining (minimal quantity of lubrication), high-speed machining (sculptured surfaces), grinding technology and new grinding wheels, micro- and nano-machining, non-traditional machining processes, and intelligent machining (computational methods and optimization). Advanced students, researchers and professionals interested or involved in modern manufacturing engineering will find the book a useful reference.
Nowadays, the use of composite materials has increased in various areas of science and technology due to their special properties, namely for these application in aircraft, automotive, defence and aerospace industries as well others advanced industries. Drilling is a frequently practised machining process in modern industry owing to the need for component assembly in composite structures. This book aims to provide the research and review studies in drilling of composite materials. The first three chapters provide information on delamination and damage reduction in drilling of composite materials. The following two chapters deal with influence of machining parameters on the delamination. The sixth chapter is focused on modelling of drilling aluminium matrix composites using artificial neural networks. The chapter seventh is dedicated study of analysis of delamination in drilling wood composite medium density fibreboards. Finally, the last chapter of this book is focused on studies on composite drilling - the state of the art. The present research book can be used as for final undergraduate engineering course (for example, mechanical, manufacturing, materials etc) or as a subject on machining/composites at the postgraduate level. Also, this research book can serve as a useful reference for academics, manufacturing and materials researchers, manufacturing, materials and mechanical engineers, professional in composites technology and related industries.
Residual stresses are a common phenomenon in composite materials. They can either add to or significantly reduce material strength. Because of the increasing demand for high-strength, light-weight materials such as composites and their wide range of applications in the aerospace and automotive industries, in civil infrastructure and in sporting applications, it is critical that the residual stresses of composite materials are understood and measured correctly.The first part of this important book reviews destructive and non-destructive testing (NDT) techniques for measuring residual stresses. Various mathematical (analytical and numerical) methods for calculation of residual stresses in composite materials are also presented. Chapters in the first section of the book discuss the simulated hole drilling method, the slitting/crack compliance method, measuring residual stresses in homogeneous and composite glass materials using photoelastic techniques, and modeling residual stresses in composite materials. The second part of the book discusses residual stresses in polymer matrix, metal-matrix and a range of other types of composites. Moreover, the addition of nanoparticles to the matrix of polymeric composites as a new technique for reduction of residual stresses is discussed.Residual stresses in composite materials provides a comprehensive overview of this important topic, and is an invaluable reference text for both academics and professionals working in the mechanical engineering, civil engineering, aerospace, automotive, marine and sporting industries. - Reviews destructive and non-destructive testing (NDT) techniques for measuring residual stresses - Discusses residual stresses in polymer matrix, metal-matrix and other types of composite - Considers the addition of nanoparticles to the matrix of polymeric composites as a new technique for reduction of residual stresses
This book offers an insight into the primary and secondary manufacturing of different class of polymer matrix composites (PMCs). The major focus is on the fabrication of a variety of PMCs with substantial coverage of various processing techniques and related advantages and limitations. The book also describes secondary manufacturing processes such as machining and joining of PMCs and provides the know-how related to developing these techniques. It discusses recently commercialized tools and techniques and highlights the opportunities provided by the design and development of newer cutting tools and machining methods. The book covers material selection guidelines, product manufacturability, product development process, and cost-estimating techniques that help readers to understand where a process fits within the overall scheme and which is appropriate for a particular component. This book provides professionals with valuable information related to composites product manufacturing as well as state-of-the-art knowledge in this field.
This excellent volume will serve as an indispensable reference and source book for process design, tool and production engineers in composite manufacturing.

This book is of interest to academicians, students, researchers, practitioners, and industrialists working in aerospace, automotive, marine, and construction industries.
Machining processes play an important role in the manufacture of a wide variety of components. While the processes required for metal components are well-established, they cannot always be applied to composite materials, which instead require new and innovative techniques. Machining technology for composite materials provides an extensive overview and analysis of both traditional and non-traditional methods of machining for different composite materials.The traditional methods of turning, drilling and grinding are discussed in part one, which also contains chapters analysing cutting forces, tool wear and surface quality. Part two covers non-traditional methods for machining composite materials, including electrical discharge and laser machining, among others. Finally, part three contains chapters that deal with special topics in machining processes for composite materials, such as cryogenic machining and processes for wood-based composites.With its renowned editor and distinguished team of international contributors, Machining technology for composite materials is an essential reference particularly for process designers and tool and production engineers in the field of composite manufacturing, but also for all those involved in the fabrication and assembly of composite structures, including the aerospace, marine, civil and leisure industry sectors. - Provides an extensive overview of machining methods for composite materials - Chapters analyse cutting forces, tool wear and surface quality - Cryogenic machining and processes for wood based composites are discussed
